Answer:

answer A. 0.5

Step-by-step explanation:

hello

as A and B are independent P(B/A)=P(B) =0.5

in short, the information provided by the event A does not impact at all the event B. so knowing A or not does not impact the probability of B.

you can use the formula as well P(B/A)=P(A and B) / P(A)=(P(A)xP(B))/P(A)=P(B)

hope this helps

Find the midpoint of the line joining A (3,5) and B(1,3)

MaRussiya [10]

Answer:

(-1 , -1)

Step-by-step explanation:

$x_1= 3 \\ y_1= 5 \\ x_2=1 \\ y_2= 3$

$midpoint \: = ( \frac{x_2 - x_1}{2} \: \frac{y_2 -y_1}{2} )$

$=( \frac{1 - 3}{2} \: \frac{3 - 5}{2} ) \\ = ( \frac{ - 2}{2} \: \frac{ - 2}{2} ) = \\ ( - 1 \: - 1)$

For an object whose velocity in ft/sec is given by v(t) = −t2 + 2, what is its displacement, in feet, on the interval t = 0 to t

Sedbober [7]

Answer:

1.333

Step-by-step explanation:

Distance travelled (or displacement) will be the antiderivative of Velocity.

Antiderivative of -t^2 + 2 =

d(t) = -t^3/3 +2t

Now plug in t=2 and t=0 and subtract them.

(-8/3+4)- (0/3 +0)= -8/3+4 = 1.333

Answer:

detail in step by step

Step-by-step explanation:

Left: ΔABC ≅ ΔDEF

DF corresponding to AC DF = 3

∠B = ∠E = 28°

Middle: DF = AC = 5

∠B = ∠E = 100°

Right: ΔLMN ≅ ΔPQR

m∠P = m∠L = 105°

QR = MN = 11.6

m∠M = m∠Q = 45°

LN = PR = 8.5
